MARTIN COUNTY, Fla.--The Florida Forestry Service has ruled the cause of a wildfire in Martin County on Sunday to be suspicious.

The cause is still under investigation, but officials say it was not the result of an authorized burn.

The fire started around noon Sunday, and spread to about 22 acres within about three hours, according to the Florida Forestry Service.

The fire spread to both the north and south sides of Salerno Road.

Fire officials say they will remain watchful for hot spots for the next day or two, making sure nothing can reignite and continue causing damage.

The Florida Forestry Service says 22 homes were at risk from the fire.

"You get the chills when you come back here, just from the potential devastation," said nearby resident Janine Wilde.

The fire spread into her backyard, covering the area with soot and burning a work shed.
